FLIER FOR SPINNING MACHINES AND THE LIKE.

Application filed July 1, 1925. Serial No. 40,800.

This invention relates to certain new and useful improvements in connection with the fliers employed on spinning machines and the like One of its objects is the provision of a flier which is readily applicable to all makes and sizes of spindles and which is provided with an improved bearing self-adaptable to the plane of rotation of the flier about the spindle.

Another object of the invention is to provide a flier of this character which is simple. compact and inexpensive in construction and efficient in operation.

In the accompanying drawings:

Figure 1 is a side elevation of the im proved flier in position on the bobbinspindle. Figure 2 is a top plan view thereof. Figure 3 is an enlarged vertical longitudinal section on line 33, Fig. 2. Figure 4 is a detached perspective view of the attaching member or anchoring sleeve of the flier. Figure 5 is similar View of the bearing members or journals thereof.

Similar characters of reference indicate corresponding parts throughout the several views. i r

The flier-body, which is adapted to be detachably mounted on the spindle 10, of a bobbin 11, is preferably in the form of a substantially hollow block, consisting of upper and lower cup-shaped sections 12, 13 suitably fastened together by a lap or inter locking joint and having alining central openings 14 extending through them. These sections are stamped from sheet metal and shaped to provide an external bead or flange 1.5 between the top and bottom of the flierbody. Surrounding the central Openings 1 1 are inwardly-facing rims or collars 16 whose opposing ends terminate short of each other to provide an intervening annular groove or channel17.

The flier wires 18 are connected to a baseplate 19 which fits tightly over the lower block section 13 below the head 15 and contains wire-retaining loops or eyes 20 at its opposite ends. The outer end of each flier wire has the usual thread-engaging eye 21 While its inner end has a laterally-bent portion 22 arranged to lie flatwise on the base plate between the flier-body and the corresponding retaining loop. The flier wire is reliably clamped in position by a rotatable locking ring 23 disposed between the base plate and the bead 15 of the flier-body. At its diametrically opposite sides, said locking ring has vertieall -oflset flanges 24 which overlap the bent portions 22 of the flier wires in the locked position thereof, the vertical webs 25 of said flanges serving to deflect or spring such bent portions of the wires laterally to hold the latter in their retaining loops 20.

Contained in the openings 14 of the flier block-sections are independent upper and lower bearing members or journal sleeves 26. upon which the flier is free to rotate. 'lhese sleeves are preferably in the form of bands or rings stamped and pressed from sheet metal, each having an annular eX- ternal flange or thrust collar 27 which eX- tends into the channel 17 between the rims of the block sections 12, 13 andwhich engages or overhangs the opposing inner edge of the corresponding rim, as shown in Fig. 3.

Fitted comparatively loosely within the. journal sleeves 26 is a vertically-split expansible anchoring sleeve or band 28 of spring steel provided between its ends and on 0pposite sides thereof with external bosses or projections 29. This expansible sleeve serves as a means for attaching or frictionally holding the flier on the tapered end of the bobbin-spindle 10 and also as a support upon which the flier is revolubly mounted. The bosses 29 of the anchoring sleeve constitute thrust bearings which are disposed between the flanged-ends of the journal sleeves 26, there being sufficient play between these parts to allow a limited movement of the flierbody lengthwise on said anchoring sleeve. Said journal sleeves are somewhatlarger in diameter than the anchoring sleeve to allow for the expansion of the latter as it is applied to the spindle.

By constructing and arranging the parts of the flier as herein shown and described, the independent journal sleeves 26 are unaf fected by the expansion of the anchoring sleeve 28, thereby always insuring a true and perfect bearing for the flier body regardless of the type or size of the spindle employed. Furthermore, the journal sleeves, as well as the other parts of the device, are stamped and pressed from sheet metal and require no machining or finishing, thereby affording a corresponding saving in time and labor and rendering their manufacture at a moderate cost.

I claim as my invention:

1. A flier for spinning machines and the like, comprising a flier-body, independent upper and lower bearing members contained in said body and about which the same revolves, and a supporting member for attaching the flier to a bobbin-spindle and having means thereon arranged to engage the opposing inner ends of said bearing members.

2. A flier for spinning machines and the like, comprising a flier-body, independent upper and lower bearing rings contained in said body and about which the same revolves, and an expansible supporting sleeve contained within said bearing rings for attaching the flier to a bobbin, said sleeve having an external projection arranged to engage the opposing ends of said bearing rings.

3. A flier for spinning machines and tne like, comprising a flier-body, upper and lower bearing members contained in said body and having thrust collars at their opposing inner ends, and a supporting menu-- ber extending through said bearing mem bers for attaching'the flier to a bobbin-spindle, said supporting member having a thrust bearing arranged to engage the opposing thrustcollars of said bearing members.

i. A flier for spinning machines and the like,comprising a flier-body having inwardly-facing rims atits upper and lower ends, independent bearing rings engaging said rims and held against outward movement relative thereto, and an expansible sleeveeiztending loosely through said bearing rings and adapted for attachment to a bobbinspindle, said sleeve having an external projection extending between the opposing in nerends of said bearing rings for limiting the relative endwise movement of the latter and said sleeve.

5. A flier for spinning machines and the like, comprising a substantially hollow flierbody having inwardly-facing rims at its upper and lower ends, the opposing edges of said rims being spaced apart to form an annular channel bearings rings engaging said rims and provided at their inner ends with external flanges extending into said channel and engaging the opposing edges oi said rims, and an expansible sleeve extending loosely through said bearing rings and adapted for attachment to a bobbin-spindle, Said sleeve having a thrust bearing against which the inner faces of said ring-flanges are arranged to abut for limiting the relative endwise movement of the bearing rings and the attaching sleeve.

6. A flierhlock for a bobbin-spindle, including a self-adjusting sleeve adapted for attachment to the spindle, upper and lower bearing rings loosely surrounding said attaching sleeve and about which the flier block revolves, the bearing-rings being independent of said flier-block, and complementary means on the bearing rings and the at taching sleeve for limiting their endwise movement relative to the flierblock 7. A flier-block for a bobbin-spindle, including a self-adjusting sleeve adapted for attachment to the spindle and having a pro jection thereon constituting a thrust-bean ing, upper and lower bearing rings applied to the flier-block and surrounding said sleeve, said rings having thrust collars at their opposing inner ends arranged to engage the thrust bearing on said sleeve, and means on the flier-block against which said thrust-ooh lars are adapted to abut to prevent outward displacement of the bearing rings relative to said block.
